VIBRATION REMOTE SENSOR BASED ON SPECKLES TRACKING, WHICH USES AN OPTICAL-INERTIAL ACCELEROMETER, AND METHOD FOR CORRECTING THE VIBRATIONAL NOISE OF SUCH A SENSOR

摘要

The present invention relates to a remote sensor based on speckle tracking, which uses an inertial-optical accelerometer. The remote sensor makes it possible to correct the speckle pattern correlation centroid value in the presence of displacements due to vibrational noise. To this end, the accelerometric device can instantaneously highlight the displacements of the CCD sensor relative to an inertial reference, i.e., of a mass immovable with respect to the fixed stars, installed in the optical axis of the sensor.
